Hi,
Which version did you update to?
According to your description, it may related with a known issue in Windows 10, version 2004
Certificates may not be present after updating that have been resolved for Windows 10, version 2004.
If you have already encountered this issue on your device, you can mitigate it within the uninstall window by going back to your previous version of Windows using the instructions here. The uninstall window might be 10 or 30 days depending on the configuration of your environment and the version you’re updating to. You will then need to update to the later version of Windows 10 after the issue is resolved in your environment.

Hope above information can help you.
